Regarding language, students have two options to choose: D (only in Basque) , which means that every subject will be taught in Basque (except for specific language subjects). Or H, (Basque + English), which means that the subjects appearing with the symbol (i) will be taught in English, and the others in Basque.
Our school offers three pathways: Humanistic, Social (both on the left side of the sheet) and Science (right side of the sheet).
The difference between Humanistic and Social is that in the Humanistic path, they study Latin, while in the Social, they study Maths applied to Social Science.
The subjects on the first block have all an X, Those are compulsory subjects. 3 sessions per week each, except for PE, which includes two sessions per week. One session = 55mn (except for Friday, where sessions last 60 mn).
As you can see in the sheet below, there are other blocks from which students have to choose one subject out of two or more, depending on the block. Those subjects include 4 sessions per week.
